The world of fungi inside seed banks

We share our planet with microbes - tiny invisible organisms that are all over the place, including on and in us. Some can potentially do us harm, some do us good and we humans host enormous microbial communities, for example our own gut microbiome. Plants also have a microbiome, and in a paper out recently, scientists working in a seed bank report how they got curious about what microbes could be stored away inside banked seeds. And by surveying seeds from just 1 type of plant, they found about 200 species of fungi. Katie Haylor spoke to author Rowena Hill.
